Kinase experiment: | Radioactive γ-P32-ATP is added to 600 mM MgATP (pH=7) solutions at volume ratios of 1:1000-1:300, depending on the lifetime of the radioactive reagent. The total volume of each reaction is 12 mL, including 6 ml of protein from size exclusion chromatography fractions (final concentration 0-50 nM for different fractions, peak fractions are used for Rbin-1 and AMPPNP inhibition), 4 mL FPLC SEC buffer with 0.6 mM Na2SO4 and 2 mL MgATP (final concentration=100 mM). The reactions are then incubated at room temperature for 30 or 60 min before quenching with 12 mL 0.2 M EDTA. 1 mL from each reaction mixture is spotted on to TLC PEI cellulose F plates. The TLC buffer contained 0.15 M formic acid and 0.15 M lithium chloride. The TLC plates are then imaged using the Typhoon Scanner 9400. ImageJ is used to calculate the densitometric ratio of the spots corresponding to radioactive free phosphate and ATP to determine the percent of ATP hydrolyzed[1]. |

Rbin-1 is an eukaryotic ribosome assembly inhibitor.
All cellular proteins are synthesized by ribosomes, whose biogenesis is a complex multi-step process quickly completed in eukaryotes. Several chemical inhibitors of ribosome function are available, however, potent validated chemical probes are still lacking to analyze the dynamics of eukaryotic ribosome assembly.
In vitro: In the mode of action study of Rbin-1, the MDR-sup fission yeast cells was chemically mutagenized and the resistant clones that can grow in the presence of Rbin-1 were isolated. Results found that each of the 13 Rbin-1 resistant clones had one of five different point mutations in the mdn1 gene. It was further confirmed that, using overexpression on plasmids in MDR-sup cells and by replacement of endogenous mdn1 in wild-type cells, all the identified mutations were enough to confer resistance to Rbin-1. In addition, Rbin-1 at 1 μM was able to inhibit the ATPase activity by around 40%. Moreover, the nuclear export of the pre-40S subunits that were tracked using two different reporters, Rps3- GFP and Rps2-GFP, could not be blocked in Rbin-1-treated cells, suggesting that Mdn1 had specific roles in pre-60S ribosome assembly [1].
In vivo: So far, there is no animal in vivo data reported.
Clinical trial: Up to now, Rbin-1 is still in the preclinical development stage.
